(I deleted my comment above before I saw your reply) Society has norms for determining right and wrong social behaviour. We teach children not to behave this way at a very early age. I'm sure these societal values aren't completely consistent across cultures and ages, but I'd be surprised if most people you ask don't characterize his language as hostile and abusive. Of course, everyone has a right to be an asshole.
